ii Mighty Mule 362-D Installation Instructions rev 07/19/11
Thank you for purchasing a Mighty Mule 362-D Gate Opener—GTO’s “do-it-yourself” automatic gate opener!
When correctly installed and properly used, your Mighty Mule Gate Opener will give you many years of reliable
service. Please read the following information and watch the enclosed video to ensure you have the correct
system for your particular needs. Furthermore, this manual and the video will enable you to properly install
your Mighty Mule Gate Opener.
The Mighty Mule 362-D Gate Opener is designed for installation on Pull-To-Open dual gate leaves (gates
that open into the property). By purchasing accessory brackets [FM148], the Mighty Mule 362-D Gate Opener
can accommodate Push-To-Open dual gate leafs (gates that open out from the property). Please see
Pull-To-Open/Push-To-Open diagram on page 3. The gates must not exceed 12 ft. or 300 lbs. per leaf (see
Technical Specifications on page 1). The Mighty Mule Gate Opener can be used on vinyl, aluminum, chain
link, farm tube, and wrought iron gates.
Use on solid (surface) gates is not recommended. Solid surface gates have a high resistance
to the wind. If the wind is strong enough, the opener will obstruct and stop, blow fuses, or
may damage the equipment.
The Mighty Mule Gate Opener features an adjustable stall force setting. This safety feature makes the gate
stop and reverse direction within 2 seconds when it comes in contact with an obstruction. The MIN setting;
means the gate will exert the minimum force on an obstruction before it stops and reverses direction. You will
need to adjust the stall force for your particular application.
The Mighty Mule Gate Opener also has an adjustable auto-close feature. After the gate reaches the fully
open position, it can be set for OFF, or to remain open up from 3 to 120 seconds before automatically closing.
Pressing the transmitter button at any time after the gate opens fully will cause it to close immediately. The
auto-close factory setting is OFF, meaning the gate will stay open until you press the transmitter (or keypad,
etc.) again.
The Mighty Mule Gate Opener accommodates extra transmitters, digital keypads, solar panels, push buttons,
automatic gate locks, and other access control products. These optional accessories (page 26) are available
at Tractor Supply stores or through Special Order (if the accessory is not in stock). If your store cannot special
order accessories, please call the GTO Sales Department (800/543-GATE) or visit www.mightymule.com.
